So I've been trying to find the write-up for Pony Satyrs for Dawn of the Fifth Age, but while search engines do point to 5e SRDs that contain a consistent write-up of the race, I cannot for the life of me find where they are in the 5e books. For reference, I own Beyond Everglow, the Campaign Setting books (Both Pathfinder and 5e), the Bestiary, the Pantheon Book (with Forgotten Gods as well, because I wasn't aware it was a compilation at the time), the two Griffon books, the Race and Tribe Compilations, and Forgotten Past.

Am I missing something? Or have I merely fallen prey to the Mandela Effect?
